NONREFILLABLE BOTTLE Filed Nov. 10, 1937 Patented May 3, 1938 UNITED STATES PATENT 2,116,447 NONRE FILLABLE BOTTLE Joseph Nozar, Sr., Cleveland, Ohio Application November 10, 1937, Serial No. 173,911

6 Claims.

,-tion of the plug into the bottle neck which prevents separation of the interlocking connection between the cap and bottle neck and necessitates the breaking of the frangible flange on the bottle neckto permit removal of the cap'and thereby with the present invention, the bottle being preferably formed of glass and carrying a relatively thin frangible flangeat the mouth thereof;

Figure'Z is a top plan view of the bottle cap showing diametrically opposite lugs for sliding interlocking reception on the flange of the bottle mouth;

Figure 3 is a bottom perspective View of the cap showing the diametrically opposite grooved lug at the open end of the cap for interlocking engagement with the flange on the bottle mouth;

Figure 4 is a fragmentary longitudinal sectional view of the bottle showing a sealing disk or gasket seated on an internal shoulder in the bottle neck below the bottle mouth flange;

Figure 5 is a longitudinal sectional view of the cap showing the spring pressed plug carried thereby for reception in the bottle neck and for engagement with the sealing disk; and

Figure 6 is a fragmentary longitudinal sectional view showing the cap mounted on the bottle neck.

Referring more in detail to the accompanying drawing, the reference character Ii] designates a bottle, preferably formed of glass and having a reduced neck H carrying at the open mouth end thereof a relatively thin outwardly directed frangible annular flange l2. An internal annular enlargement i3 is formed on the neck l2 and forms an annularshoulder or seat M for a sealing disk iii of fibrous or any suitable material disposed below the frangible flange i2.

A closure cap iii of cup-form is closed at its outer end as at ll while the inner end thereof is open as at l8. A coil spring lfi'is confined within the cap 16, one end of the spring l9 being secured to the inner face of the closed end ll of the cap while the other end of the spring is secured to a plunger or plug ZQthat normally projects below the open end N3 of the cap. The plug isof less diameter than the internal diameter of the cap 16 and at the upper end thereof that is attached to the adjacent end of'the spring IQ there is formed an annular flange 2i moving in frictional contact with the inner wall of the cap it. As' shown more clearly in Figures 3, 5, and 6, a pair of diametrically opposite lugs 2E2 depend from the lower open end it of the cap, the lugs being outwardly offset as illustrated with the inner faces 23 thereof inthe plane of the inner wall of the cap it, a groove E l being formed in the inner face of each lug 22 at the inner side 23 thereof. The external diameter of the bottle I neck I i is substantially the same as the internal diameter of the cap l6 and the lugs 22.

To place the cap it upon the bottle ill, the open end of the cap is positioned out of longitudinal alignment with the bottle neck iii to place a side edge of the spring pressed plug it in engagement with a side edge ofthe open end of the bottle neck, the part of the plug engaged with the bottle neck being located at a point between the diametrically opposite lugs 22. Downward pressure on the cap it causes the plug 20 to be moved upwardly into the cap and the cap lowered onto the bottle neck and in a position to cause engagement of the open end it at one side of the cap with the frangible flange if of the bottle neck and to align the grooves 2 5 in the lugs 22 with the bottle neck flange l2. Lateral sliding movement of the bottle cap causes the grooves 23 in the lugs 22 to receive the bottle neck flange 23 and when the cap it has been moved completely in longitudinal alignment with the opening in the bottle neck, the spring l9 will force the plug 20 downwardly into the bottle neck for engagement with the sealing disk 55. In this position, the spring pressed plug 20 prevents separation of the interlocking connection between the frangible flange I2 on the bottle neck and the grooved lugs 22 on the cap It. To open-the bottle, it is necessary to forcibly move the cap into engagement with an object or to percussively strike the cap to cause the latter to break the frangible flange I? on the bottle neck and to destroy the interlocking connection between the bottle neck flange and cap lug.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent and while there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

I claim:-

1. In a non-refillable bottle, a bottle having a relatively thin outwardly directed annular frangible flange at the mouth thereof, a sealing disk seated in the neck of the bottle below the frangible flange, a cap adapted for interlocking and non-removable mounting on the bottle, a tensioned plug carried by the cap for reception in the neck of the bottle below the flange of the bottle neck for engagement with the sealing disk, and means carried by the cap for engagement with the neck flange and prevented from separation from the plug by the position of the plug in the bottle neck.

2. In a non-refillable bottle, a bottle having a relatively thin outwardly directed annular frangible flange at the mouth thereof, a sealing disk seated in the neck of the bottle below the frangible flange, a cap adapted for interlocking and non-removable mounting on the bottle, a tensioned plug carried by the cap for reception in the neck of the bottle below the flange of the bottle neck for engagement with the sealing disk, means carried by the cap for engagement with the neck flange and prevented from separation from the plug by the position of the plug in the bottle neck, said means including diametrically opposite lugs carried by the cap and said lugs being grooved at their inner sides for reception of the bottle neck flange.

3. In a non-refillable bottle, a bottle having a relatively thin outwardly directed annular frangible flange at the mouth thereof, a sealing disk seated in the neck of the bottle below the frangible flange, a cap adapted for interlocking and non-removable mounting on the bottle, a tensioned plug carried by the cap for reception in the neck of the bottle below the flange of the bottle neck for engagement with the sealing disk, means carried by the cap for engagement with the neck flange and prevented from separation from the plug by the position of the plug in the bottle neck, said plug being in the plane of the connection between the frangible flange and cap.

4. In a non-refillable bottle, a bottle having a relatively thin outwardly directed annular frangible flange at the mouth thereof, a sealing disk seated in the neck of the bottle below the frangible flange, a cap adapted for interlocking and non-removable mounting on the bottle, a tensioned plug carried by the cap for reception in the neck of the bottle below the flange of the bottle neck for engagement with the sealing disk, means carried by the cap for engagement with the neck flange and prevented from separation from the plug by the position of the plug in the bottle neck, said means including diametrically opposite lugs carried by the cap and said lugs being grooved at their inner sides for reception of the bottle neck flange, said plug being in the plane of the connection between the frangible flange and cap.

5. In a non-refillable bottle, a bottle having a relatively thin outwardly directed annular frangible flange at the mouth thereof, a sealing disk seated in the neck of the bottle below the frangible flange, a cap adapted for interlocking and non-removable mounting on the bottle, a tensioned plug carried by the cap for reception in the neck of the bottle below the flange of the bottle neck for engagement with the sealing disk, means carried by the cap for engagement with the neck flange and prevented from separation from the plug by the position of the plug in the bottle neck, said plug being movable into the cap to permit lateral alinement of the flange engaging means on the cap with said flange whereby the cap is laterally moved into closing position on the bottle neck.

6. In a non-refillable bottle, a bottle having a relatively thin outwardly directed annular fran- I gible flange at the mouth thereof, a sealing disk seated in the neck of the bottle below the frangible flange, a cap adapted for interlocking and non-removable mounting on the bottle, a tensioned plug carried by the cap for reception in the neck of the bottle below the flange of the bottle neck for engagement with the sealing disk, means carried by the cap for engagement .with the neck flange and prevented from separation from the plug by the position of the plug in the bottle neck, said means including diametrically opposite lugs carried by the cap and said lugs being grooved at their inner sides for reception of the bottle neck flange, said plug being movable into the cap to permit lateral alinement of the flange engaging means on the cap with said flange whereby the cap is laterally moved into closing position on the bottle neck.
